java-interview-questions-answers

They didn’t teach appsec in Comp Sci or in engineering or MIS or however you learned how to program. And they probably still don’t. So how could you be expected to know about XSS filter evasion or clickjacking attacks, or how to really store passwords safely. Your company can’t afford to send you on expensive appsec training, and you’re too ...

If you got bugs, you’ll get pwned

The SEI recently published some fascinating research which shows a clear relationship between software quality and software security. The consensus of researchers is that at least half, and maybe as many as 70% of common software vulnerabilities are fundamental code quality problems that could be prevented by writing better software. Sloppy coding. Not checking input data. Bad – or no ...

Self-Signed Certificate for Apache TomEE (and Tomcat)

Probably in most of your Java EE projects you will have part or whole system with SSL support (https) so browsers and servers can communicate over a secured connection. This means that the data being sent is encrypted, transmitted and finally decrypted before processing it. The problem is that sometimes the official “keystore” is only available for production environment and ...

Signing Digital Certificates with OpenSSL Library

While working on the pgopenssltypes extension I realized that I haven’t discussed how to sign digital certificates using the OpenSSL library. (At least I don’t recall doing so – I might have discussed this in the early days of the blog. I’m pretty sure I’ve already discussed signing digital certificates with the BouncyCastle (java) library.) My pgopenssltypes extension will have ...

Adding OpenSSL User-Defined Types to PostgreSQL

PostgreSQL supports user-defined types (UDT). These types can be used to provide type-safety on user-defined functions when we would otherwise be forced to use simple BLOB objects. This comes at a significant cost. Many databases support UDT but implementation details vary widely so there’s a significant amount of vendor lock-in. In addition C language UDT require deployment via PostgreSQL extensions ...

Database Threat Models

I finally have a breather and can start working through my backlog of ideas. I start with some background that will make the motivation for subsequent posts clearer. What are the threat models for the persistence layer of an application, specificially the threats against the database itself? Remember that a ‘threat’ is an adverse act, whether intentional (by an attacker) ...

In Favour of Self-Signed Certificates

Today I watched the Google I/O presentation about HTTPS everywhere and read a couple of articles, saying that Google is going to rank sites using HTTPS higher. Apart from that, SPDY has mandatory usage of TLS, and it’s very likely the same will be true for HTTP/2. Chromium proposes marking non-HTTPS sites as non-secure. And that’s perfect. Except, it’s not ...
